November 3, 2015 – Five teams of fishery biologists from the U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS), Florida Fish and Wildlife Conservation Commission (FWC), the National Park Service (NPS), and Florida International University (FIU) sampled for non-native fishes in canals, ponds and ditches in and around the Plantation/Davie area of Broward County, FL.

The Striped Newt is a small salamander found in xeric habitats (e.g., scrub, sandhill, dry flatwoods) of the lower coastal plain and northern peninsular Florida. Though once considered "common," they are currently a candidate species for federal listing.

On November 20, 2014, eight teams of fishery biologists from the U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS), Florida Fish and Wildlife Conservation Commission (FWC), U.S. National Park Service (NPS), and Florida International University (FIU) gathered for a one-day sampling event to collect non-native fishes from canals, ponds and ditches in Miami-Dade County, FL....

Based on field research conducted during 2002-2009, the bobwhite population on the Babcock-Webb Wildlife Management Area (WMA) in Southwest Florida is incapable of supporting desired levels of sport harvest.

Habitat alteration and climate, when combined, are serious threats to amphibians and other wildlife. Habitat suitability models are being used to predict the responses of an amphibian community to hydrological and habitat restoration in the Greater Everglades Ecosystem.

Florida's springs are a source of cultural, recreational, and ecological importance. But land-use changes and increased demands for groundwater due to the state's growing population have led to widespread impairment of these unique ecosystems.

More than 110 sinkholes formed in the Dover area of Florida during a freeze event in January 2010. Ground water levels dropped to record-setting lows as farmers pumped water to irrigate their plants for protection from the cold temperatures. The sinkholes destroyed homes, roads and sections of cultivated areas.

As residential areas encroach on agricultural areas, sinkholes that once only affected croplands, can now pose greater threats to communities and infrastructure. More than 110 sinkholes formed in the Dover area of Florida during a freeze event in January 2010.

As another potentially busy hurricane season approaches, U.S. Geological Survey (USGS) scientists are sharing data and photos with the public to stress the importance of evacuation and storm preparedness.

In a cooperative research program, the USGS, NASA and the U.S. Army Corps of Engineers (USACE) are using airborne laser mapping systems to quantify coastal change along the entire coastline affected by Hurricane Katrina (http://coastal.er.usgs.gov/hurricanes/katrina/).

The USGS has posted aerial photos from the northern Gulf of Mexico coastline showing before and after conditions in response to Hurricane Katrina. The photos show five photo pairs of the Chandeleur Islands, Louisiana, and three photo pairs of Dauphin Island, Alabama. A set of ‘quick response’ photos from Bay St. Louis to Biloxi, Mississippi are also posted.

"The past several days have seen remarkable devastation resulting from Hurricane Katrina. Our thoughts and prayers are with everyone who has been affected by this disaster," said USGS Acting Director Pat Leahy. "In the aftermath of Katrina, USGS research on hurricanes and natural hazards is no longer just a scientific endeavor – it is a matter of public safety."

U.S. Geological Survey fisheries biologists in Gainesville, Fla., have confirmed the presence of the voracious non-native northern snakehead fish in Meadow Lake in Queens, N.Y. Five specimens have been collected by the New York State Department of Environmental Conservation from the lake in Flushing Meadows Corona Park since early July.

In its latest report on water use in the United States, the USGS looked at the nation's dependence on ground water. The report entitled Estimated Withdrawals from Principal Aquifers in the United States, 2000, provides details of ground-water withdrawals and use from principal aquifers in each state.
